Figure 3. Comparison of persistently infective abilities on non-cloned and cloned cells successively passaged.

Figure 3

Lane 1 and 2, normal MDBK C1–2F (without and with PK treatments); Lane 3 to 6, uncloned BSE-infected MDBK C1–2F (passage level; p11, p17, p24, and p27); Lane 7 and 9, cloned BSE-infected MDBK C1–2F (passage level; p15, p19, and p26). Molecular mass marker in kilodaltons (kDa) is shown on the left. Housekeeping protein, GAPDH (glyceraldehydes-3-phosphate dehydrogenase) was used as a control of comparative protein concentration. The result shown is representative of three independent experiments.
